Theoretical study of electromagnetic transport in Lepidoptera Danaus plexippus wing scales

open access: yesHeliyon, 2018
This paper examines the electromagnetic energies developed in the scales of the Lepidoptera Danaus plexippus. The Green tensor method was used to calculate and simulate the energies at specific wavelengths.

Temporal variation in flower-visiting insects of Calotropis gigantea in the Southern Province of Sri Lanka

open access: yesRuhuna Journal of Science, 2022
Calotropis gigantea (Giant milkweed) is a medicinal plant native to a few Asian countries including Sri Lanka. However, the plant is considered invasive in countries such as Australia, the USA and Brazil.

Generalization for both diurnal and nocturnal pollination in the mass‐flowering desert geophyte Nerine laticoma (Amaryllidaceae)

open access: yesPlant Biology, EarlyView.
Both diurnal and nocturnal pollinators are important in the desert plant Nerine laticoma. Abstract The evolutionary limits to generalization in plant pollination systems are often determined by trade‐offs in which adaptations to one set of flower visitors reduces the effectiveness of another set of visitors.

Dragon Fruit (Hylocereus undatus) Pollination in New Zealand: A Preliminary Report on Flower Visitors, Natural Pollen Deposition, and Artificial Pollination

open access: yesNew Zealand Journal of Crop and Horticultural Science, Volume 54, Issue 1, March 2026.
Dragon fruit (pitaya; Hylocereus undatus) is a promising, new high‐value crop in New Zealand. The large nocturnal flowers open for one night and close early in the morning the following day over a 3‐ to 6‐month long flowering period. In dragon fruit's native range, hawkmoths and bats are key nocturnal pollinators, and honey bees visit flowers during ...

Sex‐Specific Response to Predator Auditory Cues in Asian Corn Borer (Ostrinia furnacalis)

open access: yesEcology and Evolution, Volume 16, Issue 1, January 2026.
Females downregulate more DEGs; males upregulate under predation risk. Males boost ecdysteroid; females reduce fecundity under bat ultrasound. Female O. furnacalis reacted more strongly to auditory cues of bats than males. ABSTRACT Predation risk has profound effects on prey from phenotype to gene expression.

Strategic mowing of roadside milkweeds increases monarch butterfly oviposition

open access: yesGlobal Ecology and Conservation, 2019
The eastern North American migratory population of monarch butterflies (Danaus plexippus) has declined precipitously due, in part, to the widespread decline of its obligate host plant, milkweed (Asclepias spp.). Linear right-of-ways (e.g.

Food Subsidy Effects on Host Foraging Behavior Shape Host–Macroparasite Infection Dynamics

open access: yesEcology and Evolution, Volume 16, Issue 1, January 2026.
Wildlife behavioral responses to different distributions of food subsidies could shape encounter and infection intensity of environmentally transmitted parasites. Using a mathematical model, we show that the way in which food subsidy changes transmission rate and variation in parasite burdens (e.g., through changes in time spent foraging and variation ...

Occurrence of Interspecific Mating between Two Species of Danaus Kluk, 1780 (Lepidoptera: Nymphalidae) in Nature

open access: yesPsyche: A Journal of Entomology, 2018
Mating across species occurs rarely in nature, which contends prevalent idea of biological species concept. Throughout species range, mating pattern varies and reproductive barriers are also not fixed among different species. In this study, two instances
